The Development of Learning Achievement and Model Construction Abilities in the Science Lesson on the Topic of Lights through Blended Learning Based on STEM Education of Mathayomsuksa 3/3 Students at the College of Dramatic Arts

Abstract

This action research aimed 1) to compare the students’ learning achievement and the students’ ability to construct a model on the topic of lights in the science lesson by using the blended learning based on STEM education and 2) to compare the model construction skills on the topic of lights in the science lesson before and after using the blended learning based on STEM education. The sample group was ten Mathayomsuksa 3/3 students at the College of Dramatic Arts. The participants were selected with the purposive sampling method. The research instruments were lesson plans, pre-test and post-test of learning achievement, and model construction ability test. The mean, standard deviation, and score difference were used to analyze the data. The research revealed that 1) The learning achievement of students after using the lesson plans of Lights by using blended learning based on STEM education was higher at the mean of 13.30 (S.D. = 2.11) than the pre-test which was at the mean of 5.50 (S.D. = 1.08). 2) The model construction abilities of students after participating in the lesson plans of Lights by using the blended learning based on STEM education from the post-test was higher at the mean of 13.5 (S.D. = 2.01) than the pre-test which was at the mean of 4.20 (S.D. = 0.79).
